JAMES W. REED, OF DENVER, COLORADO, ASSIG-NOR TO THE REED INTERNATIONALMANUFACTURING COMPANY, OF DENVER, COLORADO, A CORPORATION OF GOLD- RADO.

PORTABLE GEARED ROTARY TOOL.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, JAMES W. REED, a citizen of the United States,residing in the city and county of Denver and State of Colorado, haveinvented certain new and useful Improvements in Portable Geared RotaryTools; and I do declare the follow ing to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the characters of reference markedthereon, which form a part of this specification.

My invention relates to improvements in rotary tools in which a chuck isemployed for holding a metal drill or a boring device of any kind whichmay be operated by rotary action. v

The body of the machine may vary considerably in construction and may beutilized for purposes other than the operation of chuck tools, and onefeature of my pres ent improvement consists in applying the chuck memberand its gear to the body of the device in such a manner that it may bereadily detachable, thus making it practicable to employ the body of thestructure and its gears for the operation of tools other than the rotarychuck class.

The body of the framework is equipped with a number of gears arranged tomultiply the motion transmitted from the main operating gear to thechuck, whereby a relatively low speed of the main gear when transmittedto the chuck through the agency of the speed-increasing gears, may be ashigh as desired.

Having briefly outlined my improved construction, I will proceed todescribe the same in detail, reference being made to the accompanyingdrawing in which is illustrated an embodiment thereof.

In this drawing: Figure 1 is a side elevation of my improvedconstruction. Fig. 2 is an edge view of the same looking in thedirection of arrow'2, Fig. 1. Fig. 3 is a fragmentary view looking inthe direction of arrow 3, Fig. 1. Fig. 4 is a view of the detachablechuckholder with the chuck and its gear in place. Fig. 5 is a sectionalview taken on the line 55 of Fig. 1, looking in the direction of thearrow 5.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the framework of my improved device, thisframework including two bars 6 and 7 and an interposed brace bar 8. Thisframework is angular in shape, there being a bend 9 in the bar 6intermediate its extremities, the bar 7 being curved to maintain the twobars 6 and 7 approximately parallel intermediate their extremities. Theouter extremities of these bars are connected by a handle 10, whiletheir opposite extremities are connected by a hand bar 12. To this bar12 a chuck holder 13 is secured, the said holder consisting of an arm 14provided with a lug 15 having an opening 16 to register with an openingformed in an extension 17 of the frame bar 12, a bolt 18 being passedthrough the registering openings and constituting a pivot for the arm14. To this bolt is applied a nut to secure the parts in place. The arm13 is further secured to the end bar 12 intermediate its extremities bya screw 19, which as shown in the drawing is provided with a winged head20 to facilitate manipulation. This screw passes through separated lugs21 which engage the bar 12 on opposite sides, but project inwardlybeyond the same to allow the screw to pass through the space 22 betweenthe extremities of the frame bars 6 and 7. The arm 14 curves outwardlyas shown at 28 at its extremity remote from the lug 15 and terminates inan eye 24 through which a spindle 25 passes. On the inner extremity ofthis spindle is secured a gear 26, while to its outer extremity a chuck27 is made fast, the said chuck being adapted to receive the tool 28arranged to be operated by rotary movement.

The gear 26 is arranged to mesh with a corresponding beveled gear 29occupying a position at right angles to the gear 26 and mounted on aspindle 3O journaled in the forward extremity of the frame 5 and securedin place by a nut 31. On the opposite extremity of the spindle 30 ismade fast a pinion 32 which meshes with a relatively large gear 33 faston a spindle 34 whose opposite extremity is equipped with a pinion 35meshing with a still larger operating gear 36, which is equipped with acrank 37 provided with a handle 38. The gear 36 is fast on a spindle 39journaled in the bar 6 of the framework, the said spindle as shown inthe drawing having a head 40 at one ex- Patented May 21, 1912.

tremity and a nut 41 threaded on the opposite extremity. Hence as thelarge gear 36 is rotated by means of the crank 37, relatively rapidmotion is communicated to the spindle 3 f, while the gear 33 mountedthereon further increases the speed of the spindle 80 by meshing withthe pinion 32, while the same motion imparted to the spindle 30 istransmitted to the chuck 27 through the medium of the gears 29 and 26,which are of equal size.

- Having thus described my invention, what I claim is:

1. The combination with a frame having a handhold at one extremity, aholder at the opposite extremity of the frame, achuck member journaledin the said holder, the holder being provided with an arm, the armhaving a lug provided with an opening adapted to register with anopening formed in the extremity of the frame, the arm also havingseparated members adapted to straddle the extremity of the frame, meanspassed through. the registering opening of the frame and the lug andthrough the extremities of the separated members for securing the chuckholder to the frame, an operating spindle journaled in the main frame,and a gearing connection between the operating spindle and the rotarychuck member, substantially as described.

2. The combination with a main frame member having a handhold at oneextremity, a holder arranged transversely of the opposite extremity ofthe main frame member, the said holder being pivotally connected at oneextremity with the said main frame member, and adapted to be swung uponits pivot away from the main frame member, the said holder comprising aportion offset from the main frame member, means for retaining theholder rigid with the frame, a chuck member journaled in the said offsetportion of the said holder, an operating spindle journaled in the mainframe, a connect-ion between the chuck member and the operating spindleincluding a gear carried by the chuck member, and a cooperating gearcarried by the adjacent extremity of the frame, substantially asdescribed.

3. The combination with a main frame member having a handhold at oneextremity, of a holder, a chuck member journaled in the said holder, theholder being pro vided with an arm having means thereon for det-achablyconnecting the same with the extremity of the frame opposite to thehand-hold, comprising separated members adapted to straddle the saidextremity of the frame, an operating spindle journaled in the mainframe, and a gearing connection between the operating spindle and therotary chuck member, including a beveled gear carried by the chuckmember and a cooperating beveled gear carried by the adjacent extremityof the frame, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
